The transverse spatial distribution of partons in the nucleon (generalized parton distributions) is a crucial ingredient in the description of high-energy ep and pp scattering with hard QCD processes. Experimental information about the transverse spatial distribution of gluons comes from measurements of the t-dependence of J/psi production at HERA and other processes. We discuss the physical mechanisms leading to a growth of the nucleon's transverse size at small x. Based on this information, we study the interaction of small-size color dipoles with the proton in the leading log Q{sup 2} approximation. We find that at small x and central impact parameters the dipole-nucleon interaction approaches the unitarity, or black-disk (BDL) limit. We argue that this new regime of strong interactions can be probed in central pp collisions at LHC.
